If they used a different film for each camera they tested back in the 
old days, "The Leica with Tri-X was worse grain than the Contax with 
Kodachrome II", you would have about what you have now.

The norm for testing a 35mm camera was to use the manufactures best 50mm 
lens, and Kodachome 25. That leveled the playing field. You can not have 
a meaningful comparison if there are no basic similarities. The more 
variables you can eliminate the more meaningful the test.

However, since lens and recording media are the things being measured 
you need to standardize one or the other. Since testing a digital camera 
is more like testing film you need to standardize the lens to get a 
meaningful result. It is like comparing Fujichrome and Kodachrome by 
shooting the film in two entirely different systems.
